cleanliness of the glass are good indicators of your operating
efficiency. Not enough heat is produced when only a few
pieces of wood are burned or the wood may not burn
completely.
NOTE: When loading the appliance, ensure to keep fuel back
from the glass. If coals are to accumulate on the front lip,
there is a chance they will fall out when the door is opened.
Burn only dry, clean unpainted wood that has been seasoned.
It produces more heat and less soot or creosote. Freshly cut
wood contains about 50% moisture while after proper
seasoning only about 20% of the water remains.
As wood is burned, this water boils off consuming energy that
should be used in heating. The wetter the wood, the less heat
is given off and the more creosote is produced. Dry firewood
has cracks in the end of the grain.
Firewood should be split, stacked in a manner that air can get
to all parts of it and covered in early spring to be ready for
burning the following autumn.
Cut the wood so that it will fit horizontally side to side.
5.3 SMOKING
A properly installed appliance should not smoke. If yours
does, check the following:
• Has the chimney had time to get hot?
• Is the smoke passage blocked anywhere in the appliance,
chimney connector or chimney?
• Is the room too airtight or the air intake (if installed) not
connected to the outside? Try with a window partly open.
• Is the smoke flow impeded by too long a horizontal pipe or
too many bends?
• Is it a weak draft perhaps caused by a leaky chimney, a cold
outside chimney, too large a diameter of a chimney, too short
a chimney, or a chimney too close to trees or a higher roof?
